Sorry, meant the ones I posted or this one: http://www.ledhut.co.uk/led-bulbs/e27-led-bulbs/new-4-watt-e27-led-candle-shape-bulb.html 
My understanding is you'll need a transformer/s that will drive the total power consumption (W), or your LED lights lights will flash on and off.
So if you are going to install 3x 2.5 meters of LED lights at 36W each then you'll need a transformer/s that can supply 100W.
On your 2nd point - when you switch the lights off using your light switch you will lose the last setting. To retain the setting, you will need to turn the lights off using the colour controller off switch.
I have just installed undercounter LED's and have 2 transformers driving the two seperate cupboard runs.
The LED's you're looking at are going to be very bright (2700 lumens), I have the the 120 small LED's and they are plenty bright enough at 1800 lumens.

Thanks mate thats what I thought.
Also regarding control, I was looking at getting 2 remote controllers with a single wall controller like this:
http://www.downlightsdirect.co.uk/led-rgb-wall-controller-rf.html
Would this allow me to turn them on/off from this wall controller as well?
Currently I have ordered :

But thinking to change this so I only have a single controller to control each zone and a nice wall mount
.Just cant see if it allows on/off.
Thanks!

I bought some LED bulbs! They were cost £5.00 each from Tesco and I bought 3 for my study.
They are the GU10 Philips 2W (20W equivalent). I realise it is somewhat unfair to compare these with 50W bulbs as they simply aren't supposed to be as good, however they were cheap enough for me to give them a try.
I am tall (6ft 3) and my 50W halogens warm the top of my head when I walk around the house! I bet 90%+ energy is turned into heat.
I intend to upload photos shortly as they are very good, perhaps a touch dim but a 3W version would be excellent!
A quick calculation to justify LED bulbs:
Estimated time in study on average 15 hours per week with lights on, 3 bulbs using 2W each compared to the 50W halogens. Assume 1 kilowatt hour costs £0.128 (from British Gas website).
(3 x 0.002kW) x 15hours x 52 weeks= 4.68 kilowatt hours per year. 4.68 @ 12.8 pence = £0.60 per year.
The LEDs are rated to last 10 years, so the bulbs cost an average of 50p each per year.
TOTAL COST FOR LEDS IN ONE YEAR: £2.10
(3 x 0.050kW) x 15hours x 52 weeks = 117 kilowatt hours per year. 117 @ 12.8 pence = £14.98 per year.
I will assume that one halogen bulb lasts one year, with the bulbs being purchased for £1.00 each.
TOTAL COST FOR HALOGENS IN ONE YEAR: £17.98
Net saving of £15.88 per year my study alone just for using LED bulbs!!!
Obviously the LEDs have the original purchase cost, but my calculations have shown that this £12 oncost (£5 per 10 year LED bulb - £1 halogen per 1 year halogen bulb) will still save you money in the first year.
I have 28 spotlights in my home, with 8 of these being in my living room. If I go to LEDs throughout the house then I could save a heck of a lot each year on electricity. I genuinely think I could save £150 easily.
The only way for leccy prices is up, so at a >90% energy saving per bulb LEDs are without doubt the way to go, IF they last as long as the box claims them to...but even if they only last 5 years then you will still save plenty of cash.
Also I would think that a 4W LED would easily match a 50W halogen.
When my entire living room could draw 32W (4W bulbs) instead of 400W then there is really no need to constantly badger people to turn the lights off!

Installed these (on a push-to-break switch) if anyone's interested:
They give off a cool / white light, great for a wardrobe imo. They have a nice wide beam angle. Very happy for a fiver.
Guys,
If anyone can it would really be appreciated!
I have some LED strip Light from LED hut with the SR-1009FA Driver which operates through a wireless controller and I got the http://www.downlightsdirect.co.uk/led-rgb-wall-controller-rf.html its a wall mounted unit.
Now I have wired the driver like this:
Now the controller indicates power through a small LED, now I cant figure out how to operate this through the wireless controller? It has a learning switch which I press and then press the zone on the controller and then the colour wheel but I get nothing from the LED's. Is the wiring correct?
Thanks!

Where did you get the push to break switch from please?

City Electrical Factors in Stratford-Upon-Avon. The same item is also available on Amazon:
http://www.amazon.co.uk/White-Surface-Break-Light-Switch/dp/B00403YI3I
...but it was cheaper at CEF. Just under a fiver iirc.

Hi,
Where's a good place to buy screw and bayonet ?
Where's a good place to buy screw and bayonet ?
Looking for a half decent pair of dimmable LED Globe or Candle type bulbs, large screw (e-type?), 30-40w equivalent and good quality/very long life span preferably. Any suggestions?
They're for outside lights that are dimmed normally then go bright on PIR.

You might come unstuck, as LED lamps need a special 'Trailing Edge' dimmer, so your fitting's dimmer might not work properly.

Just a word of warning for anyone that might be ordering from SimplyLED at this present time.
They seem to be non-contactable and have gone quite on the social media front, emails, contact us and live chat, where they used to be very quick in replying.
Have £70 of a £250 order outstanding for over two months now, stock came back in last month and was told they would priority ship the items, no items have arrived and since there's been no replies by any means.

Found a dimmable globe large screw in tesco, it was a Philips one but was 20w equivalent, not bright enough really

Here is a photo of my kitchen with the 4W cool white LEDs from the Ledhut.
The four bulbs in the foreground are LEDs and the ones towards the rear are halogens.
In my hallway upstairs I have got LEDs also but these are the warm white versions, which are somewhere between cool white and the halogens in colour.
After seeing how bright these 4W ones are, and looking back at the 2W ones in my study, I think that s 50W halogen would probably be equalled by a 3-3.5W LED.

I am yet to try the dimmable ones.
My study is using the 2W version of these:
http://www.amazon.co.uk/Philips-CorePro-CLEDS2WGU1030ND-GU10-2-35/dp/B00CHJECXI
Watch out though as the Philips ones are only rated to last 10000 hours (8-10 years) and other LED bulbs are rated to last double that.
Also as previously mentioned they are touch dim, but as they are instore at Tesco are well worth buying just to give LEDs a try
.Those multi-LED blubs aren't very good IMHO. From what I understand they are older technology, plus they look rubbish.
My Aurora LEDs are very bight and have just a single LED in the middle.
